Superlight Case 3D Models: STL Bases and Storage

This collection gathers 3D models built around the idea of a light or slim case: replacement bases and shells for gaming mice, rugged travel boxes, Gridfinity storage and small enclosures for boards and parts. Most of these files are made for desktop 3D printing in common filaments, and many are parametric, so dimensions can be adjusted before you slice the STL. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Superlight Case 3D Models: STL Bases and Storage»

The mouse-related files split into two groups. One group is replacement bases and shells that reduce the amount of material around the body, often with cutouts for the sensor, buttons and charging port. The other is protective boxes and travel cases with thicker walls, latches or lids, meant to hold the mouse or a similar device when it is not in use. Gridfinity files form a separate family: cases sized to the grid, half-height or full-height lids, and baseplates that hold the case in a drawer or on a bench.

When you open a model page, check the stated dimensions and scale first, then the number of separate parts and how they join — screws, snap fits or glue. Look at whether the author lists supports, orientation and material, and read the photos of actual prints to see wall thickness and surface finish. Thin walls and small features are where a light case can fail, so layer height and nozzle size matter as much as the file itself.

To widen the search, try related terms such as lightweight shell, slim enclosure, rugged box, travel case, base plate or Gridfinity insert, and combine them with the device name you want to house. Adding a size or a connector type to the query usually narrows results faster than browsing a whole category. If nothing matches exactly, a parametric model in the same family can often be resized to your part.

FAQ

Frequently asked questions

What does "superlight" mean in these case models?
It usually refers to a case or base designed with less material than the original, so the part is thinner and lighter. The exact approach varies: some files hollow out the body, others replace a solid base with an open frame.
Can I resize a case model to fit my device?
Parametric files can be edited in the original CAD tool, and some are published with adjustable parameters. For plain STL files, scaling in the slicer changes all dimensions at once, which can distort screw holes and cutouts.
Which material works for a thin case?
Authors usually state a filament and settings on the model page. Thin walls tend to benefit from a tougher filament, while parts that only sit on a desk are often printed in standard PLA. Check the listed settings before slicing.
How do I find a case for a device that is not listed?
Search for the device name together with words like shell, enclosure, base or mount, then look at similar models in the same family. A parametric design made for a comparable device is often the closest starting point.
